CAR-AXLE BOX.

SPECIFICATION forming part of Letters Patent No. 375,217, dated December20, 1887.

Application filed February 12, 1887. Serial No. 227,392. (No model.)

To all whom it may concern:

Be it known that I, JAMES J. STEVER, a

citizen of the United States, residing atOwosso,

in the county of Shiawassee and State of Michigan,have invented certainnew and useful Improvements in Oar'Oilers, of which the following is aspecification.

Heretofore in the oil-boxes of railwaycar axles it has been customary topack within the box a quantity of saturated waste, the said waste beingso arranged around the bearing of the axle that loss of oil orlubricating material was unavoidable, inasmuch as there is nothing toprevent the oil from running out at the rear side of the journal-box. Asthe result of this, the oil spreads out and flows along the axle untilit comes to the wheels, at which point it commences to drip, entailingan enormous loss of valuable on;

Another drawback to the ordinary means of oiling the bearings ofcar-axles is that the jar of the cars causes the waste and oil in thejour= nal-box to drop down and away from the axle, and as soon as itsettles and falls away from the bearing the axle will become dry andheated, and the friction generating will set the waste and oil on fire.This has often occurred and is the immediate cause of great loss inrailway property.

To obviate these drawbacks and to provide a simple, effective, andautomatic oiler for the bearings of railway-car axles are the objects ofmy invention;

Referring to the accompanying drawings, which form a part of thisspecification, Figure 1 is a plan view of my invention. Fig. 2 is alongitudinal section of a journal-box with my invention applied. Fig. 3is an end ele vation without the journal-box, the journal being insection.

Ais an axle having a bearing-surface formet on its journal B, and O isthejournal-box, in which the oil is held.

D is a frame provided with lugs E, which form bearings for a pin orpivot or hinge, F. Arms or levers G are journaled to this pivot, andthese arms or levers constitute a frame having a pin, H, connectingtheir upper extremities, said pin H forming the axle or shaft of arotatable wheel, J, having centrally-lo cated incisions K upon itsperiphery, thus forming a roller with a centrally corrugated under thecross-piece N of the frame G, andserves to support said frame at anangle, as shown in Fig. 3, and by this means keeps the wheels J againstthe bearing B of the axle. As the axle rotates it will bear upon theperipheries of the wheel J, which movement will cause them to rotatealso, and as the oil is located in the bottom of the oil-box the wheelsJ as they rotate will carry the said oil to the bearing-Snrface of theaxle by means of the indentedportions K. By this means thebearing-surfaces are kept constantly oiled,and the springs, keeping therotating wheels against the axle, will lubricate the bearings as long'asthere is oil in the box. I also provide a stop or collar, S, havingshoulders at both ends, which slide on uprights T, said collar beingalso provided with a supportingspring, U, for the purpose of keeping itcon- Stantly against the bearing of the axle, and thus preventing anyoil from passing in that direction and'toward the wheel. It will thus beseen that any oil that has passed as far back as the collarS will beturned back into the j ournal-box again, and thus all waste from thissource is prevented.

I am aware that it has been proposed to cushion beneath a journalrotatable rollers provided with corrugations, and the same being flutedthroughout their'length for convey ing the lubricant to the journal; butthis is not the equivalent of my invention, nor do I wish to claim thesame. In my invention the corrugations only extend a portion of the wayacross the periphery of the roller, thereby leaving a plain surface oneach side,which portion bears against the journal and prevents thecushion-springs from subjecting the journal to pressure against thesharp edges of the corrugations,

Therefore, what I claim as new, and wish to secure by Letters Patent,is-- l. The combination of the base-frame D, having paired lugs E E,-EE, pins F, supported in the lugs, inwardly-extending frames and aspring, V, secured to the base-frame and having arms G G, G G, andeross-bars N N, supporting the collar, substantially as de- [0 rollers JJ journaled in the ends of the arms, scribed.

and the springs L L, secured to the base-frame no 4 5 and bearing on thecross-bar, substantially as JAMLD STDVER' described. Vitnesses:

2. The combination of the base-frame D, up- I. J. STEVER, rights T T,collar S, sliding on the uprights, FRANK E. COOK.
